DESCRIPTION OF SPECIFIC FUNCTIONS
6.1 Basic operation parameter unit
Please select control method when inverter is working.
0
：
V/F method
It is used for variable speed inverter occasions where don’t demand high perf
ormance of speed control and low-frequency torque.
1
：
Sensorless Vector control
It used for the variable speed inverter occasions with high performance.
Notes
：
1. It needs use some basic parameters of load motor when inverter takes vector
control. C300 serial inverter provides those basic parameters of motor, and
those parameters were set already.
2. When basic parameters of applied motor are different from parameters
provided by inverter, those parameters must be set again (code [F1.15] ~
[F1.18]). User can get those parameters by setting code F1.20 (Parameters
self-determination).
3. When you can’t gain nameplate parameters of applied motor or you need
inverter to inverter several motors, please take V/F method.
It is used for selecting input channel of frequency instruction.
0
：
Frequency digital setting by operation panel
Setting frequency of inverter can be set by parameter F0.2 as well as by the key
on the operation panel in normal monitor mode.
1
：
UP/DW
Acc and Dec control
Running frequency is set by terminals UP and DW. And controlled terminals UP
and DW can be selected by parameters [F3.0]~[F3.3]. When UP is on, the running
frequency will increase. When DW is on, the running frequency will decrease.
When UP and DW is on or off at the same time, running frequency will be fixed.
The rate of modified frequency of terminals UP and DW is set by parameter F4.23.
F0.0 Control methods Setting range
：
0 ~ 1
F0.1 Frequency input channel / mode selection
Setting range
：
0 ~ 7
It will get prime performance when inverter matches the same capacity motor
under the method of vector control.
